ADJUSTABLE sELr-AnIeNING BEARING.

Appiieanon' fueajnecembers, ieee. serial Nd.' 153.566,

' rlhis invention relates tosupports" for the bearings lfor rotary slvixaftsl and has for its objectV the production of'a deviceot this character which is adjustable and of` which the.

resnltsjV although it is to be understood that,

the various instrumentalities of which the invention consists can be vvariously arranged and organized,` and thev invention is not` limited to AthefpreciseI arrangen'ient and organization of these instrumentalities as herein shown and described except as Vrequiredy by the scope of the appended claim.

Of the drawings l Figure 1 represents a plan of a self-aligning bearing supportembodying the principles of the'presentinvention.

Figure 2 represents a side elevation of the same.

Figure 8 represents a front elevation of the same7 and Figure 4; represents a modification of the means for adjustably mounting the swivel bearing support upon the standard.

Similar characters indicate Y like parts throughout the several figures of the drawings.

In the drawings 10 is a base adapted to be secured to any fixed member 11 by means of the bolts 12.

This base 10 is provided with an upwardly extending boss 13 in which is iixedly secured the vertical member or standard 14 Y which may be tubular as shown.

Slidably mounted upon this standard 14 is a support 15 having a split projection 16 encirclingthe standard 14.

rlhe projection 16 has oppositely disposed ears 17 through which extends a clamping bolt 18 having a nut 19 threaded thereto.

By releasing the nut 19 the projection 16 may be adjusted lengthwise of the vstandard 14 and then clamped in its adjusted position.

Above and below the end faces of the pro- Vjection 16 are split collars 2O which are locked to the standard by means of the screws 21.

f The support 15 is cylindrical and is closely adjacent the standard 14 as showir in the drawings, the rear faceofsaidsuppo'rt havingy depressions 22 therein into which pro'- ject portions ofthe Collin-S20,` as indicatedy in dotted lines in F ig. 2. c

f-The support 15 hasccntrally disposed. on its outerv face a cylindrical projection whichis litted to a depression in the swivel bearing 24. I y

The support- 15 is also provided with opposivtely disposed concentric slots 26A through which 'extend the headedv bolts 27- screwedl into the swivel beari'ng2 and preventing the displacement cfs-aid bearingfron'i4 the projection 23l while permittlng.free movement of said bearing about the axis of said.

projection to a limitedextent. y

The bearing meinber2fl has a projection 28 on itsouteiiv faceextending transversely thereof, this projectionfhaving a bore 29 extendingf from 'end'. to` vend thereof. i

AThis borey 29 is adaptedtohave a rotatable shaftmounted therein, said shaft contacting with the wall of the bore.

If desired the shaftrmay be smaller than the bore and revolvey in roller or ball bearings located within said bore. As this construction forms no part of the present invention it is deemed trate the same.

It will be noted that the bore 29 is closely adjacentthe outer face of the swivel bearing 24. thus bringing the shaft as near Vas possible to the standard 14 so that there will be the least possible overhang.

This is of great' advantage as the nearer the shaft is to the standard the less binding there is'on the movable parts andrconsequent-ly less wear.

It will be noted by referring tothe drawings that the bore through the projection 16 is of sufficient length to prevent all tilting of unnecessary Vto illusi anY the support 1,5 on'said standard,v and the Y outer face ofthe support 15 must always be parallel to the axis of said standard in any position it may be moved.

Moreoveigwith the wide .contacting faces ofthe support 15 and the swivel bearing 24 there is no -chance for one of these members to tilt relatively to the other, and the weight of the shaft in the bore 29 cannot possibly separate said members.

As a matter of fact most of the weight of the shaft will be sustained by the projection 23 on the member 15 which projection ac-` vcuratel iits the de ression inthe bearinof ZD member 24. *Y

As shown in the drawings, portions of the base extend outwardly from the standard 1e to a point beyond the bore 29 thus giving greater rigidity to the entire device.

rlhe bearing;` member has a plurality of threaded holes 2stK into any opposed two of which the screws 27 may be disposed so that the bore 29 may assume any position throughout 350".

ln other wordsthe bore 29 may be afdiusted to any desired angle relatively to the axis oit the standard 111.

li. desired a sleeve BO may be mounted within the bore of the projection 16, this sleeve surro'unding;` a threaded standard at the opposite ends ot said sleeve.

A pin 82 extending; through the upper end of said standard limits the upward movement oi the member 15.

This makes a very simple but most effective bearing` support for rotatable shait, which will automatically aline itself with said shaft.

The clamping' mechanism 18. 19 is never used to clamp the projection rigidly to the standard 14; but yis utilized only` to take up the wear so that the bore of the projection 16 will always nicely tit the standard 14. Consequently the support is tree at all times to move about the axis of thel standard 1li. i

By means oit' these two moven'ients, that is the movement of the support 15 about the vertical axis of the standard 11i and the movement of the bearing` member 211 about the horizontal axis of ne support 15, it is evident 'that the bearing member 24 will accommodate itself automatically to any angle that the support shaft may assume.

It is believed that the operation and many advantages of the invention willbe well understood without further description.

Having thus described my invention, I claim:

rlfhe combination oi' a standard having an unbroken cylindrical surface; a support adjustable lengthwise thereof and adapted to itreely more about the'axis thereof, said sup porthaving a cylirdrical disk provided with a plurality ot concentric slots; a bearing member provided with a cylindrical iiange in contact with said disk, said iiangehaving a plurality of sets of threaded holes therein; and headed members extending` through said slots into either set of holes in said bearing men'iber and freely movable lengthwise of said slots.
